Efficacy and Safety of HepaSphere Drug-Eluting Bead Transarterial Chemoembolization Combined with Hepatic Arterial Infusion Chemotherapy as the Second-Line Treatment in Advanced Hepatocellular Carcinoma.

Purpose: Recently, hepatic arterial infusion chemotherapy (HAIC) has also gained popularity for hepatocellular carcinoma (HCC). Several studies have compared HAIC and Transarterial chemoembolization (TACE). However, comparisons between TACE plus HAIC and HAIC are rarely reported. Here, we evaluated the performance of HepaSphere DEB-TACE combined with HAIC (Hepa-HAIC) compared to HAIC in patients with advanced HCC. Patients and Methods: In this retrospective study, we enrolled 167 patients diagnosed with advanced HCC and treated at Peking University Cancer Hospital from May 2018 to May 2022. The cohort comprised 74 patients who received HepaSphere DEB-TACE combined with HAIC-FOLFOX (Hepa-HAIC) and 93 patients who received HAIC-FOLFOX. Over 60% of patients received prior treatments. To avoid selection bias, propensity score matching was applied to the efficacy and safety analyses. The primary endpoints are progression-free survival (PFS) and overall survival (OS); the secondary endpoints include objective response rate (ORR), disease control rate (DCR), and safety. Results: Propensity-matching yielded 48 pairs, and group baselines were almost equal after matching. Median PFS and median OS were both higher in the matched Hepa-HAIC cohort (median PFS: 8.9 vs 5.8 months, p = 0.035; median OS: 22.4 vs 9.5 months, p = 0.027), which was consistent with pre-matching analysis. The ORR in the Hepa-HAIC and HAIC cohorts was 75.0% and 37.5%, respectively; the DCR was 93.8% after Hepa-HAIC and 81.3% after HAIC. There was no treatment-related death. Grade 3-4 ALT elevation was more frequent in the Hepa-HAIC group (33.3% vs 8.3%, p = 0.003), while vomiting was more frequent in the HAIC group (29.2% vs 12.5%, p = 0.084). Conclusion: The Hepa-HAIC group is superior to the HAIC group in metrics of PFS, OS, ORR, and DCR, which indicates the combination of HepaSphere DEB-TACE and HAIC may lead to improved outcomes with a comparable safety profile in advanced HCC.

High-dose oxaliplatin induces severe hypersensitivity reactions and high recurrence rates during rechallenge in patients treated with hepatic arterial infusion chemotherapy.

AIM: To analyze the risk factors for oxaliplatin (OXA)-induced severe hypersensitivity reactions and identify the recurrence rate of the reactions after an OXA rechallenge in patients treated with hepatic arterial infusion chemotherapy (HAIC). METHODS: Among the 2251 patients treated with HAIC (OXA), 84 patients with gastrointestinal cancer who displayed hypersensitivity reactions between May 2013 and May 2022 were included in this study. Among the 84 patients, 23 (27.4%) developed severe anaphylactic reactions (grade III/IV), and 61 (72.6%) developed grade I/II reactions. We explored the risk factors for severe OXA-induced hypersensitivity reactions. Twenty-seven patients with grade I/II reactions underwent retreatment (HAIC with OXA), and the recurrence rate of the hypersensitivity reactions was determined. A multivariate logistic regression model was used to analyze the risk factors for OXA-induced hypersensitivity reaction. RESULTS: In the study, multivariate analysis indicated that the dose of OXA (odds ratio [OR] 3.077, 95 % confidence interval [CI] 1.106-8.558, p = 0.031) was an independent risk factor for OXA-induced severe hypersensitivity reactions. Twenty-seven patients with non-severe hypersensitivity reactions underwent retreatment HAIC with OXA and 14 (51.9 %) experienced HSR recurrence, including 2 (7.4 %) who experienced hypersensitivity shock. CONCLUSIONS: The administration of OXA doses is a risk factor for OXA-induced severe hypersensitivity reactions in patients treated with HAIC (OXA). Rechallenging HAIC with OXA appears to be associated with a higher recurrence rate of the HSR.

A Novel Nomogram for Predicting the Overall Survival in Patients with Unresectable HCC after TACE plus Hepatic Arterial Infusion Chemotherapy.

BACKGROUND AND AIM: Transarterial chemoembolization combined with hepatic arterial infusion chemotherapy (TACE-HAIC) has shown encouraging efficacy in the treatment of unresectable hepatocellular carcinoma (HCC). We aimed to develop a novel nomogram to predict overall survival (OS) of patients with unresectable HCC treated with TACE-HAIC. METHODS: A total of 591 patients with unresectable HCC treated with TACE-HAIC between May 2009 and September 2020 were enrolled. These patients were randomly divided into training and validation cohorts. The independent prognostic factors were identified with Cox proportional hazards model. The model's discriminative ability and accuracy were validated using concordance index (C-index), calibration plots, the area under the time-dependent receiver operating characteristic curve (AUC) and decision curve analyses (DCAs). RESULTS: The median OS was 15.6 months. A nomogram was established based on these factors, including tumor size, vein invasion, extrahepatic metastasis, tumor number, alpha fetoprotein (AFP), and albumin-bilirubin (ALBI), to predict OS for patients with unresectable HCC treated with TACE-HAIC. The C-index of the nomogram were 0.717 in the training cohort and 0.724 in validation cohort. The calibration plots demonstrated good agreement between the predicted outcomes and the actual observations. The AUC values were better than those of three conventional staging systems. The results of DCA indicated that the nomogram may have clinical usefulness. The patients in the low-risk group had a longer OS than those in intermediate-risk and high-risk groups (P<0.001). CONCLUSION: A prognostic nomogram was developed and validated to assist clinicians in accurately predicting the OS of patients with unresectable HCC after TACE-HAIC.

A randomized phase II trial of hepatic arterial infusion of oxaliplatin plus raltitrexed versus oxaliplatin plus 5-fluorouracil for unresectable colorectal cancer liver metastases.

Background: The purpose was to compare the efficacy and safety of hepatic arterial infusion (HAI) of oxaliplatin plus raltitrexed (TOMOX) to those of oxaliplatin plus 5-fluorouracil (FOLFOX) for unresectable colorectal cancer liver metastases (CRCLM). Methods: Patients with unresectable CRCLM were randomly assigned to receive HAI of TOMOX or FOLFOX. The primary end points were progression-free survival (PFS) measured from the date of randomisation until the date of disease progression and objective response rate (ORR). The secondary end points were overall survival (OS) measured from the date of randomisation until the date of death from any cause, disease control rate (DCR), and adverse events. Results: 113 patients were randomly assigned. With a median follow-up of 39.5 months, the PFS was 5.8 months [95% CI, 4.838-6.762]) and 4.6 months [95% CI, 3.419-5.781; P = 0.840], and the median OS was 17.6 months [95% CI, 13.828-21.372] and 13.1 months [95% CI, 11.215-14.985; P = 0.178] for the FOLFOX and TOMOX arm, respectively. The ORR were 26.1% vs 22.4% and DCR were 80.4% vs 71.4% in the FOLFOX and TOMOX arms. The most common severe adverse event was elevation of liver enzymes and pain, which did not differ in the two arms. Conclusion: HAI chemotherapy was effective for unresectable CRCLM. HAI of FOLFOX has similar efficacy to TOMOX, and HAI of TOMOX had shorter arterial infusion time. Clinical Trial Registration: https://clinicaltrials.gov/, identifier NCT02557490.

Real-world study of hepatic artery infusion chemotherapy combined with anti-PD-1 immunotherapy and tyrosine kinase inhibitors for advanced hepatocellular carcinoma.

Aim: We investigated the efficacy and safety of hepatic artery infusion chemotherapy (HAIC) combined with anti-PD-1 immunotherapy and tyrosine kinase inhibitors (TKIs) for advanced hepatocellular carcinoma (HCC). Method: This retrospective study included HCC patients treated with HAIC, TKIs and anti-PD-1 antibodies between May 2019 and November 2020 in our hospital. Primary end points were progression-free survival and safety. Results: Twenty-seven advanced HCC patients were analyzed. The median follow-up was 12.9 months (range: 4.0-24.0 months) and the median progression-free survival was 10.6 months. The objective response rate and disease control rate were 63.0 and 92.6%, respectively. No treatment-related deaths occurred. Conclusion: In patients with advanced HCC, treatment with HAIC, anti-PD-1 antibodies and oral TKIs was effective and safe.

Lay abstract Some tyrosine kinase inhibitors (TKIs) that inhibit tumor vessel growth, such as sorafenib and lenvatinib, have been recommended as first-line treatment for advanced hepatocellular carcinoma (HCC). In hepatic artery infusion chemotherapy, chemotherapeutic drugs can be delivered via a microcatheter to the tumor-supplying artery to increase the local drug concentration, leading to higher local disease control rates and less toxicity than systemic chemotherapy. The combination of anti-PD-1 immunotherapy plus TKIs was shown in a previous study to be a safe and effective treatment for advanced HCC. This study explored the safety and effectiveness of hepatic artery infusion chemotherapy, TKIs and an anti-PD-1 antibody for the treatment of advanced HCC and found that combination therapy is effective, with good tolerability.

Combination Therapy of Chemoembolization and Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma with Portal Vein Tumor Thrombosis Compared with Chemoembolization Alone: A Propensity Score-Matched Analysis.

BACKGROUND: Survival of patients with portal vein tumor thrombosis (PVTT) is extremely poor; transarterial chemoembolization (TACE) is a treatment for patients with HCC and PVTT. Some studies showed that hepatic arterial infusion chemotherapy (HAIC) might improve the survival of HCC with PVTT. There were few researches of combining TACE with HAIC for patients with HCC and PVTT. AIM: This study was aimed at comparing overall survival (OS) and progression-free survival (PFS) following treatment with conventional transarterial chemoembolization plus hepatic arterial infusion chemotherapy (cTACE-HAIC) or conventional transarterial chemoembolization (cTACE) alone in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT). METHODS: From January 2011 to December 2016, 155 patients with HCC and PVTT who received cTACE-HAIC (cTACE-HAIC group) (n = 86) or cTACE alone (cTACE group) (n = 69) were retrospectively evaluated. Propensity score matching (PSM) reduced the confounding bias and yielded 60 matched patient pairs. The tumors' responses were evaluated using the modified response evaluation criteria in solid tumors (mRECIST). OS and PFS of groups were compared using the Kaplan-Meier method, log-rank test, and Cox proportional hazard regression models. RESULTS: The median follow-up duration was 93 months (range: 1-93 months). The cTACE-HAIC group's OS (9.0 months) and PFS (6.0 months) were significantly longer than the cTACE group's OS (5.0 months) and PFS (2.0 months) (p = 0.018 and p = 0.045, respectively) in the matched cohort. Multivariate analyses showed that cTACE-HAIC was independently associated with OS (hazard ratio (HR) 0.602, p = 0.010) and PFS (HR 0.66, p = 0.038). The matched groups did not differ regarding grade 3 or 4 adverse events. CONCLUSION: cTACE-HAIC was superior to cTACE alone regarding OS and PFS in patients with HCC and PVTT. Treatment-associated toxicities were generally well tolerated.

γ-Glutamyltranspeptidase as a Prognostic Biomarker in Advanced Hepatocellular Carcinoma Treated with Transarterial Chemoembolization.

PURPOSE: To evaluate the prognostic value of pretreatment serum γ-glutamyltransferase (GGT) level in patients with advanced hepatocellular carcinoma (HCC) receiving transarterial chemoembolization. MATERIALS AND METHODS: This retrospective study included 140 patients (123 male, 17 female; mean age, 56.9 y ± 12.0; range, 22.0-82.0 y) with Barcelona Clinic Liver Cancer class C HCC who received first-line conventional chemoembolization between December 2013 and March 2018. Patients were divided into low and high GGT groups based on a cutoff value calculated with a receiver operating characteristic curve. Overall survival (OS) was compared between groups by log-rank test. Univariate and multivariate survival analyses were performed. RESULTS: The optimal cutoff values of GGT were 119.5 U/L in men and 175.0 U/L in women. The 6-, 9-, and 12-mo OS rates were 81.7%, 72.4%, and 62.9%, respectively, for patients in the low GGT group (n = 44) and 58.8%, 35.7%, and 28.8%, respectively, for patients in the high GGT group (n = 96; P < .001). Multivariable Cox regression analysis identified high pretreatment serum GGT level (hazard ratio [HR], 2.71; 95% confidence interval [CI], 1.67-4.40; P < .001), multiple tumors (HR, 3.05; 95% CI, 1.23-7.53; P = .02), and performance of target treatment (ie, sorafenib; HR, 0.41; 95% CI, 0.24-0.72; P = .002) or ablation (HR, 0.35; 95% CI, 0.18-0.66; P = .001) as independent prognostic factors for OS. CONCLUSIONS: Pretreatment serum GGT level was an independent prognostic factor for OS in patients with advanced HCC treated with chemoembolization, suggesting that GGT is a useful prognostic biomarker for advanced HCC.

Transarterial chemoembolization with hepatic arterial infusion chemotherapy plus S-1 for hepatocellular carcinoma.

BACKGROUND: Transarterial chemoembolization (TACE) and hepatic arterial infusion chemotherapy (HAIC) have shown promising local benefits for advanced hepatocellular carcinoma (HCC). S-1, a composite preparation of a 5-fluorouracil prodrug, has proven to be a convenient oral chemotherapeutic agent with definite efficacy against advanced HCC. AIM: To evaluate the efficacy and safety of TACE followed by HAIC with or without oral S-1 for treating advanced HCC. METHODS: In this single-center, open-label, prospective, randomized controlled trial, 117 participants with advanced HCC were randomized to receive TACE followed by oxaliplatin-based HAIC either with (TACE/HAIC + S-1, n = 56) or without (TACE/HAIC, n = 61) oral S-1 between December 2013 and September 2017. Two participants were excluded from final analysis for withdrawing consent. The primary endpoint was progression-free survival (PFS) and secondary endpoints included overall survival (OS), objective response rate, disease control rate and safety. RESULTS: In total, 115 participants (100 males and 15 females; mean age, 57.7 years ± 11.9) were analyzed. The median PFS and OS were 5.0 mo (0.4-58.6 mo) (95% confidence interval (CI): 3.82 to 6.18) vs 4.4 mo (1.1-54.4 mo) (95%CI: 2.54 to 6.26; P = 0.585) and 8.4 mo (0.4-58.6 mo) (95%CI: 6.88 to 9.92) vs 8.3 mo (1.4-54.4 m) (95%CI: 5.71 to 10.96; P = 0.985) in the TACE/HAIC + S-1 and TACE/HAIC groups, respectively. The objective response rate and disease control rate were 30.9% vs 18.4% and 72.7% vs 56.7% in the TACE/HAIC + S-1 and TACE/HAIC groups, respectively. Grade 3/4 adverse events had a similar frequency in both treatment groups. CONCLUSION: No improvements in tumor response rates, PFS or OS were observed with the addition of S-1 to TACE/HAIC in advanced HCC. Both treatment regimens had a similar safety profile.

AIMS: This study aims to observe the preliminary clinical efficacy of percutaneous interstitial brachytherapy using iodine-125 seeds for the treatment of advanced malignant lung tumors. SUBJECTS AND METHODS: This retrospective study enrolled 24 patients in our hospital with advanced malignant lung tumors between June 2013 and November 2017. Computed tomography (CT)-guided iodine-125 seed implantation therapy was administered to these patients. All patients were followed up at 3, 6, and 12 months after the operation. The clinical efficacy was evaluated by CT. RESULTS: Among the 24 patients, the objective response rates at 3, 6, and 12 months after the procedure were 50.0%, 50.0%, and 33.3%, respectively. Recent occurrence of adverse reactions were observed, including four cases of pneumothorax, three cases of hemoptysis, and two cases of particle displacement. CONCLUSIONS: CT-guided percutaneous interstitial brachytherapy with iodine-125 seeds can be used for the treatment of lung malignant tumors. Its clinical curative effect is remarkable and it results in limited trauma, reducing the incidence of adverse reactions and improving patient quality of life.

Safety and efficacy of hepatic arterial infusion chemotherapy with raltitrexed and oxaliplatin post-transarterial chemoembolization for unresectable hepatocellular carcinoma.

OBJECTIVE: To investigate the safety, efficacy, and prognostic factors of hepatic arterial infusion chemotherapy (HAIC) with raltitrexed and oxaliplatin post-transarterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (uHCC). METHODS: Thirty-seven patients with uHCC who received HAIC with raltitrexed and oxaliplatin post-TACE between June 2014 and December 2016 at our hospital were recruited. The primary endpoint was overall survival (OS), and secondary endpoint was progression-free survival (PFS). The overall response rate (ORR) was evaluated using the modified Response Evaluation Criteria in Solid Tumors. Toxicity was assessed according to the Common Terminology Criteria for Adverse Events (v4.0). The OS and prognostic factors were analyzed using the Kaplan-Meier method, log-rank test, and Cox regression models. RESULTS: Three (8.1%) patients achieved complete response, 17 (46.0%) patients achieved partial response, and the ORR was54.0%.The median OS and median PFS were 19.0 months and 12.0 months, respectively. The common toxicities included grade 3-4 increased aspartate aminotransferase levels (8/37,21.6%), grade 1-2 hyperbilirubinemia (75.7%, 28/37), nonspecific abdominal pain and fever, and grade 2-3 thrombocytopenia (18.9%, 7/37); no patients developed grade 3-4 neutropenia. Univariate analysis showed that the tumor diameter (≤50 mm, p = 0.028), Barcelona Clinic Liver Cancer (BCLC) stage (p = 0.012), hepatitis B virus DNA level (p = 0.033), and derived neutrophil-to-lymphocyte ratio (dNLR; derived neutrophils/leukocytes minus neutrophils) (p = 0.003) were predictive factors for prognosis. Multivariate analysis showed that patients with BCLC stage B disease (p = 0.029) and dNLR≤2 before therapy (p = 0.004) had better prognosis. CONCLUSIONS: HAIC with raltitrexed and oxaliplatin post-TACE is a safe and efficacious therapy for patients with uHCC; in particular, those with BCLC stage B and dNLR≤2 have better prognosis.
